pre-unlock — Notification of a path unlock attempt.

Description

The pre-unlock hook runs whenever someone attempts to
remove a lock on a file. It can be used to create policies
that specify which users are allowed to unlock particular
paths. It's particularly important for determining policies
about lock breakage. If user A locks a file, is user B
allowed to break the lock? What if the lock is more than a
week old? These sorts of things can be decided and enforced
by the hook.

If the pre-unlock hook program returns a non-zero exit
value, the unlock action is aborted and anything printed to
stderr is marshalled back to the client.
